Like the core Java implementation, any attempt to modify the created immutable instance will throwUnsupportedOperationException. Now, let’s explore different ways of creating immutable instances. 5.1. UsingImmutableSet.copyOf() Simply put, theImmutableSet.copyOf()method returns a copy of all the el...
EnumSetis a high-performanceSetimplementation for enum types. All of the members of an enum set must be of the same enum type. Internally, it is represented by a bit-vector, typically a singlelong. Enum sets support iteration over ranges of enum types. For example, given the enum declarati...
Note that this implementation is not synchronized. If multiple threads access a hash set concurrently, and at least one of the threads modifies the set, itmustbe synchronized externally. This is typically accomplished by synchronizing on some object that naturally encapsulates the set. If no such ...
All general-purpose sorted set implementation classes should provide four "standard" constructors: 1) A void (no arguments) constructor, which creates an empty sorted set sorted according to the natural ordering of its elements. 2) A constructor with a single argument of typeComparator, which cre...
For naming conventions and restrictions see Azure infrastructure services implementation guidelines. customData string Specifies a base-64 encoded string of custom data. The base-64 encoded string is decoded to a binary array that is saved as a file on the Virtual Machine. The maximum length ...

Attributes RegisterAttribute JavaTypeParametersAttribute Remarks Returns a set backed by the specified map. The resulting set displays the same ordering, concurrency, and performance characteristics as the backing map. In essence, this factory method provides a Set implementation corresponding to any Map...

Basically, if you need to set a large number of bits, or bits at extremely high offsets, you probably want to use this Sparse BitSet. All other alternatives are essentialy off the table; the Java BitSet class is a non-starter. Performance is superior in almost all cases to the standard...
